I think with BMW High tag tool you can chnage it when you read eeprom from key, I am not 100% sure.

try this on E series:

get into car, close door, put your seatbelt on, lock, unlock, than lock and hold it while you start.

keys should now update with info in CAS. but it is kinda weird that after 100km you still have old km value in keys. usually, you drive 20km (without interruption) and keys should update info from CAS.

Maybe was short distance drives.

find someone with tmpro...it is free function.

Must read write key data with tag key tool work 100%

[GameTheoryOptimal]

do you have a step by step process to do so? (with tag key tool)
or are you talking about the 1000 Euro function they sell? (key inspector)
